Answer to Question #85611 in General Chemistry for taha

Question

CaCl2 + Na2CO3 → ? + ?

Consider the reaction between calcium chloride and sodium carbonate (shown above). What are the formulas of the two products of this reaction?

Answer 1

Under the mixing of solutions of different salts, they dissociate and their ions recombine. The ions replace each other based on their charges as either a cation or an anion. Such chemical equation in aqueous solution is irreversible if one of the products formed is insoluble.

The balanced equation for above reaction can be written as follows

CaCl₂ (aq) + Na₂CO₃ (aq) → CaCO₃ (s) + 2NaCl (aq)
